UHE1V122MHD

The Nichicon UHE1V122MHD is a radial-lead aluminum electrolytic capacitor in the UHE series, offering 1.2 mF (1200 µF) capacitance at a 35 V rating for general-purpose electronic designs. It combines a compact radial can (φ12.5 × 30.5 mm) with specifications aimed at low impedance and long operational life.

Key electrical characteristics include low impedance (78 mΩ), a tanδ of 0.12 (20°C, 120 Hz), rated ripple currents of 2.12 A (120 Hz) and 2.65 A (10 kHz), leakage current of 420 µA, and an operating temperature range of −40°C to 105°C with a rated life of 10,000 hours at 105°C.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a rated voltage of 35 V and tolerance of −20% to +20% at 20°C, 120 Hz.
• Low Impedance and Loss — Rated impedance 78 mΩ and a tangent of loss angle (tanδ) of 0.12 at 20°C, 120 Hz, supporting lower ESR-related losses in power circuits.
• High Ripple Current Capability — Low-frequency ripple current 2.12 A at 120 Hz and high-frequency ripple current 2.65 A at 10 kHz to handle dynamic load conditions.
• Long Endurance — Lifetime/endurance specified at 10,000 hours at 105°C, reflecting the UHE series’ focus on high reliability.
• Wide Temperature Range — Rated for operation from −40°C to 105°C to support a broad range of environments.
• Compact Radial Package — Radial lead, can-style package with dimensions φ12.5 × 30.5 mm and 5 mm lead spacing (±0.5 mm) for through-hole assembly.
• Leakage Current — Specified leakage current of 420 µA after applied rated voltage and stabilization period.
• RoHS Compliant — Conforms to RoHS requirements as indicated in product data.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Power Supply Filtering — Used for bulk smoothing and ripple reduction on 35 V rails where high ripple current capability and low impedance are required.
• Decoupling and Bulk Storage — Provides bulk capacitance for energy storage and decoupling on power distribution nodes in general-purpose circuits.
• Industrial Electronics — Suited for electronic control modules and equipment that require extended high-temperature endurance and robust ripple handling.
• Consumer Electronics Power Modules — Fits through-hole power modules and assemblies that need compact, low-impedance capacitance with predictable leakage and loss characteristics.

Unique Advantages

• Designed for continuous ripple loading — High rated ripple currents (2.12 A at 120 Hz, 2.65 A at 10 kHz) reduce stress on boards and downstream components under dynamic loads.
• Measured low impedance — 78 mΩ impedance supports stable voltage regulation and lower heat generation in power paths.
• Extended high-temperature life — 10,000-hour rating at 105°C enables reliable operation in elevated-temperature environments.
• Compact radial can — φ12.5 × 30.5 mm package provides significant capacitance in a small footprint for through-hole builds.
• Predictable electrical behavior — Specified tanδ (0.12) and leakage current (420 µA) help designers budget losses and standby drain precisely.
• Flexible procurement — Offered in bulk or bag packing to match assembly and stocking preferences.
